JULIUS FINCK, OF SAN FRANCISCO, CALIFORNIA.

DOOR OPENER AND CLOSER.

T0 60% whom, it may concern.-

Be it known that I, JULIUS FINCK, a citizen of the United States, residing at the city and in the county of San Francisco, and State of California, have invented certain new and useful Improvements in Mechanical Door Openers and Closers; and I do hereby declare the following to be afull, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

This invention has relation to certain new and useful. improvements in a mechanical opener and closer for doors; and it consists of the parts and details of construction, as will be hereinafter more fully set forth in the drawings and described and pointed out in the specification.

My invention is adapted more especially for use in connection with tenement-flats, so as to enable persons occupying the second or third floor to readily open or close the outer door without necessitating the going down stairs for such purpose, thereby saving. great labor and time to the occupants by providing against the unnecessary running to the door in order to ascertain the cause of ringing the bell.

The object of my invention consists in providing a device which shall be simple in its construction, effective in its operation, and less expensive than any device of a similar nature heretofore known to me.

Referring to the drawings forming a partof this applicatiomin which similar letters and figures of reference are used to denote corresponding parts throughout the entire specification and several views of the drawings,

Figure 1 is a view in elevation showing a Patent No. 460,820, dated October 6, 1891.

Serial No. 356,932. (No model.)

showing the stroke of the operating-lever necessary to cause the opening of the door; Fig. 9, a similar View showing position assumed by several parts when door is open, the same being in position to permit the downstroke of the operating-lever in order to close the door; Fig. 10, a detail view showing door open and its connection with the operatingrod. Fig. 11 is a front elevation of plate F, with the levers F and F and the movable disk II removed, the parts which are shown 0ccupying the same position as in Fig. 7. Fig. 12 is a rear elevation of lever F; and Fig. 13 is a rear elevation of lever F, showing the movable disk pivoted thereto.

The letter A is used to indicate an ordinary door, and B the operating-handle passing through opening a, formed in the doorjamb A. The handle is shown as attached to the door-jamb merely for the purpose of better illustrating the working thereof. In practice the same will be located at the head of the stairway. To the jamb A, upon the inside thereof, I secure the plate B, which is provided with the face-piece b, adapted to be flush with the face of saidjamb. An opening l) is formed in said plate, within which the door-catch a fits. Projecting from the inner face of the plate 13" is the lug b upon which the lever O is secured and revolves. I also secure upon said lug, in front of lever O, the spring 0, which has its free end attached to the lever C. Said lever is attached to the sliding plate C through the medium of the pin 0. This pin works in the elongated slot 0, formed in saidsliding plate.

The letter indicates the catch-operating lever, which is pivoted to said plate by means of the pin 0 and is provided with the enlarged head The downwardly-hanging catch-operating lever is attached to the sliding rod or plate C by means of pin c and as the rod moves forward or backward, as hereinafter described, said lever is carried therewith. In order to provide against the lever G being carried too far up by the resiliency of the spring 0', I provide the stop or lug e, which serves at the same time to cause the sliding rod 0 to move downward with its forward movement by reason of the inclined enlarged inner end 6' coming in con tact therewith.

Beneath the door-frame I locate the bellcranks E, E, E and E The bell-cranks E and E are considerably smaller than the ones E E and are secured in front thereof upon the same bolt or projection, as clearly shown. I secure to said bell-cranks the wires 1, 2, 3, 4, 5, and 6. The wire 2 is secured to bellcrank E and inner end of the operating-handle B, while the wire 1 is secured to hellcrank E and end of operating-lever O. ires 4 and 3 connect, respectively, with bell-cranks E E and E E, as clearly indicated in Fig. 1. The wires 6 and 5 connect, respectively, with levers F F.

The letter F represents the plate secured to the rear of the door-jamb F and to which the hereinafter-described operating mechanism is secured- Upon the projecting lug f,,I locate the sleeve, (not shown,) and to said sleeve I secure the spring f, the free end of which I attach to the lug f located above said lug f. I also secure to the sleeve working upon the projecting lugf the operating-lever F in front of the springf. Said lever is providedwith the downwardlyprojecting portion f and has secured thereto the inwardly-projecting lug or pin f which is adapted to engage with the outer shoulder j of the sliding rod H, as hereinafter described. ened to the projecting lug g, which is surrounded by a spiral spring. One end of said spring I attach to the lever F and the other to projection g. To the end 9 of said lever is secured the inwardly-projecting lug which is adapted to engage with the inner shoulder j of the sliding rod H. To the inner face of said lever is attached the movable disk H by means of the pin h. Said'disk is provided with outwardly and in wardlyextench ing lugs h 'h The operating-lever F has an inwardly-projecting lug 7L attached thereto, which engages with the outwardly-projecting lug h, secured to the disk H. The outer end of the sliding bar or rod II has the upwardlyextending shoulder 71 formed thereon, while the inner end is made bifurcated, so as to form arms 7;. Said rod is held in adjusted position by means of the lugs or pinsjj, se-

- cured to the plate above and below the same,

and at the outer and inner ends has the shoulders 7' formed thereon. Between the arms 6 of thesliding rod H is secured pivotally the vertical lever I. The lower end of said lever is movably secured upon the projecting lug I, while its upper end is provided with an elongated opening for the purpose of adjusting its stroke and is secured within the opening Z, formed in the door-operating rod K. Said rod is held in position by means of the hanger 7t, and the outer end thereof is re duced in order to fit between the arms Z, formed by the bifurcated end of the rod L. The outer end of said rod is also bifurcated, thereby forming arms Z between which the outer end of rod L is pivotally secured by means of the pin Z Said rod fits into the opening m, formed in the rear of the door A,

The lever F is fastand is held in position by means of spring L located and secured therein.

In order to secure rapidity in the opening and closing of the door, I locate and secure the roller M within the opening m, formed within the front piece it of the plate F which bears against the rods L and L as the door is opened and losed and tends to press the same tightly inward at an incline.

In order to open the door, the handle B is pressed down until the projecting shoulder 11 of the enlarged portion comes in contact wit-h the stop B lrVith the downward movement thereof the inner end of the same is thrown upward, carrying therewith, through the medium of the wire 2, the bell-crank E, which, by reason of thewire connection hpulls forward the bell-crank E, which in turn,'acting upon the wire 6, causes the operating-lever F to de scend. \Viththisdownwardmovemcntoflever F the movable disk 11 is in the position illustrated in Fig. '7-that is to say, with-its lugh directly in the path of movement of lug h of lever F. It therefore follows that with the continued downward movement of lever F lug 72/3 will contact with lug h, which will have the effect of moving disk H upon its pivot and bring lug h to bear firmly against lever F, and thereby also cause the downward movement of the outer end of said lever. The positions of the levers F and F after the handle B has completed its full stroke are shown in Fig. 8. When the outer end of lever F is thus moved downward, it throws the lug g thereof into engagement with the inner shoulder j of bar H, thereby causing said bar to move inwardly toward the end M of plate F I/Vith this movement the upper end of the vertical lever I is thrown in the same direction, which causes a similar movement of the operatingrod K and forces the door open, said door, by reason of the jointed rods L L, being allowed to swing upon its hinges. As the rod K is forced inward the roller M presses against the inclined face of rods L L, and thereby gives greater impetus to the swing of the door, and

IIO

at the same time materially assists the action of the operating mechanism. As the outer end of lever F is moved, as above described, the inner end is forced up, and by reason of the wires 5, 3, and 1 and small bell-cranks E E serves to cause the lever O to descend, which throws the sliding rod O inward, and by reason of its connection with verticallever C the latter is forced in a like direction against the door-catch until said catch is released from engagement with the opening 77.. hen the catch is released, the door opens through the medium of the before-described mechanism. WVhen the door is thus open, it will be seen that the sliding rod has been moved from the position shown in Fig. 7 to that shown in Fig. 9, so that the lug h is farther inward. If now pressure upon the handle B be removed, lever F will fiy back to its normal position and consequently withdraw the pressure of lug h from h, which permits the outer end of lever F to move upwardly, as well as the outer end of the movable disk. Inasmuch, however, as the lug 71 is now located farther inward, the outer end of the disk will be prevented from fully returning to its normal position by reason of lug 7L2 of said disk coming in contact with said lug 72 Consequentlylug it of the disk is prevented from returning to its initial position andis nowout of the path of movement of the lug 72f upon lever F.

If now it is desired to close the door, the outer end of stop B which is fulcrumed at o, is thrown upward, so as to release the inner end from contact with the projecting shoulder Z) upon the downstroke of the handle. The handle is then pulled downward to its full extent, which necessarily throws the inner end upward and causes wire 2 to draw upward upon bell -crank E. This upward movement through the medium of bell-crank E and wires 4 and 6 causes the downward movement of operating-lever F, and the lug its not being in line with lug 71. of the disk the two lugs of course will not contact and the portion f of lever F will be thrown into contact with shoulder j of the sliding bar and cause the same with the continued downward movement of said lever to slide outward to its normal position. As the sliding bar moves outward, the vertical lever I, which is secured to the inner end thereof, is drawn in the same direction, and inasmuch as said lever is connected to the operatingrod K it necessarily moves the same therewith. The rod K in turn, being connected to the rear of the door by means of the rods L L, causes the closingof the same. It is also to be noticed that as the sliding bar moves outward the-lug 71, formed on the outer end of disk II, moves out of contact with the upwardly-extending shoulder h of the sliding rod II and allows said disk to move into its normal position, so as to cause the lug 7t to move beneath lug its, so as to be in line of contact therewith ready for the next opening of the door.

In order to provide against the levers F and F moving upward too far, I provide the stops N N, with which the said levers come in contact upon their upper stroke.

I am aware that minor changes may be made in the details of construction and arrangements of parts herein shown and described without creating or causinga departure from the nature and scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure protection in by Letters Patent of the United States, 1s-
